Thanks for the query, Practicing yoga especially sirsasana is good for hairs as it increase the blood circulation to the scalp,,,so, continue with that... Protein rich diet and vitamins and minerals are essential for healthy hair growth...yes you shoud take 1mg/kg/day of proteins through natural or processed source... But remember hairfall is not always due to lack of nutrients as in androgenetic alopecia which has multifactorial causes like hormonal, environmental and genetic causes...Which i think is true in your case... I advice you to in addition to lifestyle modification you should include topical medications like minoxidil 5% twice a day for 3-6 months over the effected area for better results... Hope you find it helpful
